Firewall Settings for APIs

Do not use these IPs for SIP. This page is for API traffic only (Call Cadence, CDR webhooks, SMS traffic, and related services).

Add the following IP addresses to your firewall/ACL to receive API traffic from the Smart Carrier network. Smart Carrier maintains five geographically distributed endpoints for redundancy.

Location	IP Address	Subnet
US East I (Virginia)	3.229.183.76	/32
US East II (Virginia)	3.212.1.11	/32
US West I (California)	52.55.221.115	/32
US West II (Washington)	35.168.149.159	/32
US West III (Oregon)	50.16.105.238	/32

It is highly recommended to add all IPs to your firewall configuration. The Smart Carrier network automatically routes API requests to your platform from the most responsive location.

Network and Firewall Information for Routing Inbound and Outbound Traffic

Below are the IPs you should use to either route your traffic to the Smart Carrier platform, or route calls away from Smart Carrier, for your firewall or your carrier’s firewall.

Scenario	IPs to Provide	Example
When routing outbound calls to another carrier through the Smart Carrier Platform	`209.200.231.97` and `209.200.241.97`	You are sending calls to a carrier XYZ through the Smart Carrier platform.
When receiving inbound calls from telephone numbers on the Smart Carrier network, we will send calls from the following IPs	`209.200.231.161` and `209.200.241.161`	You have telephone numbers on the Smart Carrier network and, when that telephone number is called, we will send it to your network from these IPs.
You’ve added a carrier and want that carrier to send inbound (telephone number) traffic to the Smart Carrier platform for processing and routing	`155.138.219.207` or `104.238.145.138`	You have telephone numbers from a different provider and you want to use the Smart Carrier Platform to process and route your inbound calls from that carrier.
You’ve created a Prefix in Outbound and would like to have your calls route to the Smart Carrier platform and treated based on your Prefix’s settings	`155.138.235.95` or `64.176.213.101`	You’ve created a Prefix in the Outbound section and now want to send your calls to Smart Carrier for processing.
